As the /rules endpoint is fairly new, it does not have the same stability guarantees as the overarching API v1. In such cases, we can make use of pushgateway. For metrics from workers, you can use an already ready . Writing metrics exporter for Prometheus using Python In the previous articles, we have talked about monitoring using Prometheus and other ways. By having a standard format exposed by a wide variety of integrations, you gain access to metrics that you'd have to otherwise figure out how to extract yourself.
